Upgrades to your tank can be purchased from robot factories, each of which offers a single product. The most important of these is the Polycrete, which allows you to repair the huge impassable craters that are left in the ground by enemy fire. This adds a puzzle element to the game, as you aim to kill tanks in wide areas where possible, to prevent boxing yourself in. Keep an eye on the scanner in order to avoid landmines, and don’t allow your shields to be destroyed.
